Yield:81171-71-3 98%
Reaction Conditions:
with sodium carbonate in chloroform at 20;
Steps:
4-Bromo-2-fluoro-1-isothiocyanatobenzene
Thiophosgene (66.5 mL, 86.8 mmol) was slowly added to a suspension of sodium carbonate (18.4 g, 17.4 mmol) and 4-bromo-2-fluoroaniline (15.0 g, 78.9 mmol) in CHCl3 (500 mL). The mixture was stirred overnight at RT, then filtered. The filtrate was concentrated to give product as a white solid (18.0 g, 98%). 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 7.05 (t, J=8.22 Hz, 1 H) 7.22 - 7.28 (m, 1 H) 7.34 (dd, J=9.10, 2.05 Hz, 1 H).
